Description

Technical Field

[0001] The utility model relates to the field of seats, in particular to a seat base structure. Background Art

[0002] The existing seat base is generally composed of a chassis and a fixing plate, which are buckled together to form a hollow structure. A control structure is set in the hollow structure to control the lifting and lowering of the seat, the backrest angle and other adjustments.

[0003] For example, the patent document with announcement number CN209018137U discloses a wire-controlled seat chassis, including a chassis, a tailgate, a fixed plate, a first rotating shaft, a second rotating shaft and a third rotating shaft. The chassis and the fixed plate are rotationally connected through the first rotating shaft, the chassis and the tailgate are rotationally connected through the second rotating shaft, the tailgate and the fixed plate are rotationally connected through the third rotating shaft, and the chassis has a reclining elastic adjustment mechanism, a reclining locking mechanism and a lifting mechanism.

[0004] However, in the above technology, the top edge of the chassis contacts the fixed plate, and the contact area is small. When the human body pushes the backrest backward, relative movement occurs between the top edge of the chassis and the fixed plate, thereby generating abnormal noise.

[0005] Therefore, a seat base is proposed to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the present utility model is to provide a seat base, which has the advantage of preventing the seat back from generating abnormal noise.

[0007] The technical solution adopted by the utility model to solve the problem is: a seat base structure, comprising: a bottom plate and a fixed plate, the bottom plate is provided with two supporting parts, the supporting parts are provided with folded edges, and the folded edges are in contact with the fixed plate.

[0008] As a further improvement of the above technical solution, the base plate and the support portion are integrally formed.

[0009] As a further improvement of the above technical solution, a silencer is provided on the fixing plate, the silencer is in contact with the folded edge, and the silencer is made of a flexible material.

[0010] As a further improvement of the above technical solution, a connecting column is provided on the top of the silencer, and a socket is provided on the fixing plate, and the socket is plugged into the connecting column.

[0011] As a further improvement of the above technical solution, the silencer is a rubber pad.

[0012] As a further improvement of the above technical solution, it also includes a mounting plane, and the support parts are located on both sides of the mounting plane.

[0013] The beneficial effects of the present invention are as follows: by arranging the folding edge, the contact area between the bottom plate and the seat fixing plate can be increased, and the force-bearing area can be increased. At the same time, a silencer is arranged on the fixing plate, thereby preventing abnormal noise caused by friction between the bottom plate and the seat fixing plate.

[0018] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0019] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0021] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0022] Reference Figures 1 to 2 A seat base structure includes a base plate 1 and a fixed plate 5. The base plate 1 is provided with two support portions 2. The support portions 2 are provided with folded edges 21, which contact the fixed plate. When the base plate 1 and the fixed plate 5 are assembled, the base plate 1 contacts the fixed plate 5 via the folded edges 21, resulting in a large contact area and less prone to abnormal noise.

[0023] As a preferred embodiment, the base plate 1 and the support portion 2 are integrally formed.

[0024] As a preferred embodiment, a silencer 3 is provided on the fixing plate 5, and the silencer 3 is in contact with the folded edge 21. The silencer 3 is made of a flexible material. Since the silencer 3 is made of a flexible material, when relative displacement occurs between the bottom plate 1 and the fixing plate of the seat, the abnormal noise caused by friction between the metals can be eliminated.

[0025] As a preferred embodiment, a connecting column is provided on the top of the muffler 3, and a socket 51 is provided on the fixing plate 5, which is plugged into the connecting column to facilitate assembly.

[0026] As a preferred embodiment, the sound-absorbing member 3 is a rubber pad.

[0027] As a preferred embodiment, it further includes a mounting plane 4 , the support portion 2 is located on both sides of the mounting plane 4 , and the mounting plane 4 is used to install the reclining elastic mechanism.

[0028] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
